On the isotropy of differential Ore extensions
Rene Baltazar, Leonardo Duarte Silva, Grasiela Martini
Let Ah = k[x][t; d] be the differential Ore extension. We study the action of the automorphism group of Ah on the derivations of Ah and explicitly describe, using Nowicki's decompo…
Weak Hopf algebras arising from weak matched pairs
Graziela Fonseca, Grasiela Martini, Leonardo Silva
This work extends the idea of matched pairs presented by Majid in \cite{Majid} and Takeuchi in \cite{Takeuchi} for the context of weak bialgebras and weak Hopf algebras. We introdu…
Partial (co)actions of Taft and Nichols Hopf algebras on algebras
Graziela Fonseca, Grasiela Martini, Leonardo Silva
In this paper, we characterize suitable partial (co)actions of Taft and Nichols Hopf algebras on algebras, and moreover we get that such partial (co)actions are symmetric. For cert…
